Alright Shadow, I'll bite.
If I made a Clan called [TRKY] (turkey) and talked about Thanksgiving all the time, and Muse said they were doing a Thanksgiving special, I wouldn't jump to any conclusions.
But if they started putting Turkeys with little hats on all the ships, I would say something.
In this case, the Cake came before the GoIO Birthday.
And just as a cake is representative of a Birthday, a top hat is representative of Steampunk.
No really, Google Image Steampunk.
Lots of top hats.
So, the same argument could be made that, really, this is just a Steampunk representation of the generic item my Clan is based around.
What if Muse is really not referencing any of us, and just had a generic Steampunk cake in honor of their birthday.
Nahhhhh
